Hi Law350,
All I can say is - 'Do it, Do it, Do it'
I don't know much about the Jap ones, but I picked up my Zed last saturday she's 'Girt Lush'. I love it.
But on a serious note mate (from one Zed virgin to another), This site is fantastic. I did loads of research here finding out what to look out for etc. Fire away with your questions mate, the guys here are nuts, they are a 'Font of Nissan Knowledge'.
